Sikh does not possesses personal deities, but uses a Guru system instead that is unique to the Sikh religion.

Sikhism may form in any Hindu province that borders a Muslim one after the year 1499. The mean time to happen is 360 months, but it will decrease to 144 months if the province is Doaba. After the first province is converted, it will obtain the religious center modifier, giving a -5% Local Missionary Strength penalty for those who try to convert the religious center.
